Are you concerned about the rising costs of your energy bills? Or perhaps while looking for a device that will stop your cats from getting up the chimney, you are also on the hunt for an eco-friendly chimney draught solution? Then you’ll soon be wondering why you hadn’t invested in our durable chimney draught excluder earlier.

An ideal investment for the climate conscious – the Chimney Sheep is a highly efficient energy saving device, which is also 100% biodegradable. Operating very much like a chimney plug, the Chimney Sheep blocks the airflow through your chimney, in order to prevent warm heat (and cats) from escaping and cold draughts from invading – It’s a chimney draught solution!


How do I stop chimney draughts with Chimney Sheep?

Hailed as one of Kevin Mcloud’s Green Heroes,  the Chimney Sheep is made from the highly durable, insulating and naturally hygroscopic wool of the Herdwick sheep. Once inserted into your chimney flue, the 4.43 tog rated Chimney Sheep acts like a duvet, to not only block airflow, but to insulate your chimney, whilst naturally permitting sufficient ventilation.

In contrast to inflatable chimney blockers and chimney umbrellas, which require a small gap to be left in your flue to allow ventilation, the woollen pad of the Chimney Sheep compresses to fit flues of all shapes and sizes. Leaving no gaps for draughts, your chimney will breathe through the Sheep’s natural wool fibres, which therefore prevent heat loss far more efficiently than any other chimney draught excluder.

How do I use my chimney draft excluder?

To ensure that your Chimney Sheep can do its job correctly, you must first measure the narrowest part of your flue and then select a sheep that is an inch or two bigger than your flue opening.

To use your 8″ Round Chimney draught excluder, simply push its wool head up your flue and then give it a gentle tug down, to ensure it’s got a good fit. Each sheep comes with a 6” extension rod, which in addition to the sheeps 6” handle, will give your handle a total reach of 12” (30cm).
